ScrollView嵌套ViewPager，ViewPage动态设置高度，嵌套事件冲突——滑动冲突解决方法

發布時間：2023/12/10 编程问答 34 豆豆

生活随笔收集整理的這篇文章主要介紹了 ScrollView嵌套ViewPager，ViewPage动态设置高度，嵌套事件冲突——滑动冲突解决方法小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1、創建自定義ViewPager

public class ViewPagerForScrollView extends ViewPager {int myh=0 ;boolean ifme =false;public ViewPagerForScrollView(Context context) {super(context);Log.i("lgq","高度==111= " );}public ViewPagerForScrollView(Context context, AttributeSet attrs) {super(context, attrs);Log.i("lgq","高度==22== " );TestObServernotice.getInstance().addObserver(deleteObserver);}private Observer deleteObserver = new Observer() {@Overridepublic void update(int id, int intparam, String param, Bitmap bitmap) {if (id == 111) {myh = intparam;ifme = true;}}};@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {int height = 0;if (ifme){View child = getChildAt(myh);child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));int h = child.getMeasuredHeight();height = h;}else {for (int i = 0; i < getChildCount(); i++) {View child = getChildAt(i);child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));int h = child.getMeasuredHeight();Log.i("lgq","高度==== " +h);if (h > height)height = h;}}heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY); // heightMeasureSpec = MeasureSpec.makeMeasureSpec(h, MeasureSpec.EXACTLY);super.onMeasure(widthMeasureSpec, heightMeasureSpec);} }

2、ScrollView屬性

<ScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:focusable="true"android:focusableInTouchMode="true">

3、通知刷新viewpager的高度

@Override public void onPageSelected(int i) {mViewPager.requestLayout();TestObServernotice.getInstance().notifyObserver(111, i, "6666", null);Log.i("lgq","經理===== "+i); }

?實現樣式

長高度內容? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?短高度內容

解決事件沖突方法：

自定義重寫View添加如下方法

public void setNestedpParent(ViewGroup parent) {this.parent = parent; }

@Overridepublic boolean dispatchTouchEvent(MotionEvent event) { // LgqLogutil.e("分發listview2222222");if (parent != null) {parent.requestDisallowInterceptTouchEvent(true);}return super.dispatchTouchEvent(event);}

設置事件攔截——停止事件傳遞

HorizontalListView horizontalListView = holder.getView(R.id.myhoriz); horizontalListView.setNestedpParent((ViewGroup)horizontalListView.getParent());
